Subheading notes
Legal provisions clarifying the scope of certain specific HS subheadings.
Subheading notes are legal provisions that clarify the scope of certain specific Harmonized System subheadings. Fewer in number than section and chapter notes, they are used when differentiation at subheading level requires additional clarification that the texts alone cannot provide.
In accordance with GIR 6, classification within subheadings of the same heading is legally determined by the texts of those subheadings and the relevant subheading notes, with section and chapter notes applying mutatis mutandis. Subheading notes apply only at subheading level and do not modify the scope of headings themselves.
A classic example is Subheading Note 1 to Chapter 71, which defines "platinum" and "gold" for subheading purposes, with specific purity thresholds applying only at this nomenclature detail level.
In practice, subheading notes are often decisive in classification disputes involving fine technical distinctions between similar products. Unfamiliarity with them can lead to classification errors with significant financial consequences.
